GnYMNASTIC APPARATUS.

Specification of Letters Patent.

Application filed. January 25, 1913. Serial No. 744,190.

Patented Jan. 27, 1914.

To all whom it may concern Be it known that 1, CHARLES G. Rosannnncnn,citizen of the United States, residing at Savannah, in the county ofWayne and State of New York, have invented certain new and usefulImprovements in Gymnastic Apparatus, of which the following is aspecification.

This invention relates to gymnastic apparatus and is designed moreparticularly as an improvement on the apparatus shown in m co-pendingapplication Serial Number 711,851, filed July 27, 1912. g

It is one aim of the invention to provide a novel means for supportingthe ends of i the horizontal bar or trapeze bar of the apparatus uponthe uprights, the means permitting of vertical adjustment of the bar toany desired height.

The invention further aims to so construct the uprights of theapparatus, that while they may be adjusted as to length so as to bear attheir ends against the floor and ceiling of the room in which theapparatus is arranged, adjustment of the horizontal bar supportingmembers upon the uprights will not be interfered with,

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is aperspective view of the apparatus embodying the invention. Fig. 2 is adetail vertical sectional view through the lower portion of one of theuprights. Fig. 3 is a vertical sectional view in detail through one ofthe supports for the horizontal bar.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying draw ingsby the same reference characters.

In the drawing, the apparatus is illustrated as including a pair ofspaced uprights between which the horizontal bar or trapeze bar extends.Each of these uprights is indicated in the drawing by the numeral 1 andeach is provided at its upper end with a head 2 having a socket 3receiving said upper end of the upright. Each head 2 is provided uponits upper side with a facing 4 of felt or any other like material whichwill prevent injury to the ceiling against which the head is disposed,and which will also enable the head to bear more firmly against theceiling.

1 9 and provide for free rotative movement of the stem 8, although theuprights may have a firm bearing in the said socket.

In order that the stem 8 may be rotated and thereby adjusted, it isprovided below its socket 9 with a head 11 having a number of sockets 12for the engagement of a spanner-wrench. The base 5 is provided on itsunder side with a facing 13 of felt, or the like, designed to preventinjury to the floor surface upon which the base is disposed. In orderthat the stem 8 may be held at adjustment, a lock collar 14 is threadedadjustably onto the stem and is arranged to bear at the upper end of thesleeve 6, as illustrated in Fig. 2. At this point it will be understoodthat by engagement of the spanner-wrench with the head 11, the uprightsmay be adjusted so that its head 2 and base 5 will bear firmly againstthe ceiling and floor, respectively.

Each of the members mentioned above for supporting the ends of thehorizontal bar includes a sleeve 15 which is interiorly tapered in thedirection of its upper end as indicated at 16 and at its upper and lowerends is interiorly threaded as at 17 and 18, respectively.

A collar 19 is threaded into the upper end of the sleeve 15 and asimilar collar 20 is threaded into the lower end thereof, the collarshaving portions projecting respectively above and below the respectiveends of the sleeve and in their projecting por tions being formed withopenings 21 for the engagement of the spanner-wrench, whereby thecollars may be rotated and thereby adjusted in the sleeve. Arrangedwithin the sleeve '15 is a binding sleeve consisting of two or moresections 22 which are interiorly cylindrical and exteriorly conical.

By referring to Fig. 3 of the drawing it will be observed that uponmovement of the binding sections 22 upwardly within the sleeve 15, theywill be caused to approach each other and thereby bind firmly againstthe upright 1 which they embrace,

and it will also be observed from inspection of this figure that thelower or major ends of the said sections 22 rest upon the upper end ofthe collar 20 so that by threading this collar into the lower end of thesleeve the sections will be forced upwardly for the purpose stated. Inthis manner, the supporting member as a whole may be secured at anypoint of its adjustment upon the respective upright. The collar 19 isprovided for the purpose of forcing the binding sleeve sections 22downwardly and out of binding engagement with the respective upright 1,when it is desired to adjust the supporting device and after the collar20 has been unthreaded for a short distance. Projecting laterally fromthe sleeve 15 is the fixed member 23 of a socket in which the end of thehorizontal bar 24, is received. This member of the socket issubstantially semi-cylindrical and has its concave side presentedupwardly and the socket is encircled by a cap-member 25 which is alsosubstantially semi-cylindrical and which is disposed upon the upper sideof the bar 24 after the end of the bar has been fitted into the member23.

The sections of the socket are held assembled by a screw 26 insertedthrough the opening 27 in the member 26 and threaded into the opening 28in the member 23, this screw passing also through an opening formed inthe end of the bar 24.

Having thus described the invention what is claimed as new is 1. I11 asupporting structure, an upright, a support adjustably mounted thereonand including a sleeve interiorly tapered, tapered binding membersarranged within the sleeve, and a collar adj ustably threaded into thesleeve and bearing against the major ends of the binding members.

2. In a supporting structure, an upright, a support adjustably mountedthereon and including a sleeve interiorly tapered in the direction ofits upper end, binding mem bers arranged within the sleeve andexteriorly tapered in the direction of their upper ends, and acollaradjustably threaded into the lower end of the sleeve and bearing Copiesof this patent may be obtained for five cents each, by addressing theCommissioner of Eatents, 1

against the major ends of the binding members.

3. In a supporting structure, an upright, a support adjustably mountedthereon and including a sleeve interiorly tapered, tapered bindingmembers arranged within the sleeve, and a collar adjustably threadedinto each end of the sleeve, one of the collars being arranged to bearagainst the binding members at one end and the other collar beingarranged to bear against the said members at the opposite end.

l. In a supporting structure, an upright, a support adjustably mountedthereon and including a sleeve interiorly tapered, tapered bindingmembersarranged within the sleeve, and collars adjustably threaded intothe sleeve in the opposite ends thereof and bearing against the saidmembers at their opposite ends. 7

5. In a supporting structure, an upright, a support adjustably mountedthereon and including an interiorly tapered sleeve, tapered bindingmembers arranged within the sleeve and adjustable longitudinally of thewall thereof whereby to bind the upright embraced thereby, and means foradjusting the said binding members.

6. 'In a supporting structure, an upright, a support mounted thereon andincluding a sleeve interiorly tapered, binding sleeve sections fittedwithin the sleeve and exteriorly conical, and collars adjustablythreaded into opposite ends of the sleeve and bearing against theopposite ends of the binding sleeve sections.

7 In a supporting structure, an upright, a support mounted thereon andincluding a sleeve, the sleeve having a fixed socket member projectinglaterally therefrom and having a concave upper side, a socket memberremovably assembled with the fixed socket member, and means connectingthe said members.

In testimony whereof I aflix my signature in presence of twowitnesses.
